Contact supplierCooling towers are a relatively new sector for ozone treatment. As such, the benefits of the technology are still being discovered by the users in this sector. The main advantages of ozone water treatment over the traditional chemical water treatment are in the water and energy savings that can be made. The reduction, and possible elimination, of chemical use also creates cost
Contact supplierDisinfection is the killing of infectious agents outside the body by direct exposure to chemical or physical agents. However, chemical disinfectants only work if surfaces have been thoroughly cleaned first to remove grease and other dirt. For effective disinfection, it is important to first clean the surface and remove visible dirt, food particles and debris, and then rinse to remove any residue.
Contact supplierResearch is continuing to evaluate this phenomenon. At the doses typically used in UV disinfection, microbial repair can be controlled and accounted for as discussed in section 3.1.1. 2.3.3 UV Dose and Dose Distribution UV dose is a measurement of the energy per unit area that is incident on a surface.
